How To Fix Cisvc.exe High CPU Usage

Cisvc.exe  is a Windows operating system file and is part of the Windows indexing service – also known as the “Content Indexing Service”.  However, there are actually two items that use this name, one legit and one not so much.

The real Cisvc.exe process is to ensure that the Windows indexing service does not over utilize your computer’s memory (RAM) and CPU resources. It is also responsible for monitoring Cideamon.exe to ensure that low memory problems do not occur and it normally goes unnoticed as it operates when the computer is not busy performing other tasks.

The other Cisvc.exe one is actually a keylogger and may have been installed on your PC as part of the Family Keylogger program (it spies and records the actions of other users on your computer), or as part of a trojan or shady spyware application.

  1. Go to the Start menu and select Control Panel.

  3. Click the Add/Remove Windows Components option.
  4. Uncheck the box next to Indexing Service and then click Next.
  5. Click Finish. Windows Indexing Service is now disabled on your computer.
